Title: Improvements relating to self-closing reversible chucks
IPC: B23B31/163
Filed: 1969-04-03
Abstract: 1,220,914. Chucks; work supports. EMERSON ELECTRIC CO. 3 April, 1969 [15 May, 1968], No. 17505/69. Headings B3B and B3T. A self-closing reversible chuck comprises a spindle 10 driven by a reversible motor through a driving gear 12, a scroll plate 30 attached to an end flange 14 of the spindle 10 and a chuck head relatively rotatable on the spindle 10 and comprising a flanged sleeve 18, a cap member 24, and work clamping jaws 72 movable radially in ways in the cap member 24. Friction brake band 40 attached to fixed spindle bearing support structure 36 enables the chuck head to be rotated with the spindle 10 when the torque on the workpiece gripped by the jaws reaches a predetermined value, and when stop members 70a and 70b abut one another when the jaws are fully open. The chuck also includes workpiece centring means comprising pivotally connected links 84 which are also connected by pins 86 to the radially movable jaws 72. The rear end of the spindle 10 includes radially movable jaws 90 and pivotally connected links 84<SP>1</SP>, and also a friction brake band 58, a scroll plate 50 and a relatively rotatable head 48, 52, working similar to the front end, for centring the rear end of a workpiece. Constructional details.-The scroll plates 30 and 50 include three eccentric cam tracks (66a), (66b), (66c), (Fig. 5, not shown) in which shoes 80 move to radially move the jaws 72. The full radial movement of the jaws is achieved in 180 degrees movement of the shoe round its cam track; continued movement to 360 degrees reversing the direction of movement of the jaw. Each jaw 72 includes an insert 75 retained by spring plunger 76 which is tiltable about an axis parallel to the spindle axis. Since the workpiece is gripped to a degree depending on the torque acting on it, if there is any tendency for slip the inserts 75 will tilt and dig in to the workpiece. The friction of the brake band 40 is adjustable by means of an adjusting screw (40d) (Fig.2 , not shown).

Title: Improvements in or relating to operating mechanism for chucks
IPC: B23B31/20
Filed: 1950-07-17
Abstract: 689,646. Chucks. ARON, E., and PULMAN, W. E. R. April 30, 1951 [July 17, 1950], No. 17872/50. Class 83 (iii). In operating mechanism for collet chucks, a shaft 14, consisting of two portions of different diameters has a pinion 15 on its smaller portion through which it is driven and a collet 17 within a bevelled sleeve 16 in its larger portion. Balls 29, between coned abutment rings 27, 28, are engaged by an axially movable coned encircling sleeve 34, and are thereby moved radially to urge the abutment rings axially. The abutment ring 27 engages balls 23 in holes 22 in the shaft 14, the balls 23 being surrounded by a resilient ring 25 and engaging a toroidal track on a sliding member 21 which abuts the sleeve 16. Axial movement of the encircling sleeve 34 urges the balls 29 radially, and the abutment ring 27, balls 23, sliding member 21 and sleeve 16 axially, thus opening or closing the collet 17, The abutment ring 28 is held axially by a dished spring washer 30 engaging a sleeve 31 splined on the shaft 14. The sleeve 31 is positioned axially by a nut 32 which can be locked to the pinion 15 and provides a means of adjusting the tension in the dished spring washer 30. The washer 30 allows the abutment ring 28 to move leftwards should the diameter of work inserted in the chuck be such as to prevent the sleeve 16 moving its full distance to the right; thus strain on the working parts is avoided.

Title: Electro magnetic device
IPC: H01F38/02
Filed: 1953-06-30
Abstract: 749,605. Automatic voltage regulation. BALINT, A. T. June 30, 1953 [July 3, 1952], No. 18082/63. Class 38 (4). In Fig. 2 variations of an alternating voltage connected to terminals CD are detected by a transformer primary windings 3, 4 of which are connected in series across the terminals and wound on cores 1 and 2 of different magnetic material. The B-H curves for the two materials intersect so that, at a predetermined voltage, equal fluxes are produced by windings 3, 4 and there is no output from a winding 6 on a centre limb 5. Deviation of voltage from this value produces from winding 6 an output of corresponding phase-sense which is so applied in series at MN as to produce a constant voltage at terminals EF. Alternative arrangements of transformer are described in which the cores of different material are separate and windings are in series, or parallel or are common to the two cores. An arrangement involving a single composite core common to both primary and secondary windings is described. In Fig. 9 there is no secondary winding and the deviation voltage is obtained from points k, l at which primary windings 17, 18 are connected in series with equal impedances ZK across the variable voltage source. The deviation voltage may itself constitute a source of stabilized voltage if the operating range of the magnetic materials is suitably chosen.

Title: Improvements in or relating to Radio Direction Finders
IPC: G01S3/14
Filed: 1962-05-10
Abstract: 1,154,501. Radio direction-finding. TELEFUNKEN PATENTVERWERTUNGS - G.m.b.H. 10 May, 1962 [10 May, 1961], No. 18106/62. Heading H4D. In a radio direction finding antenna system, a number of identical horn antennµ are mounted in a circle, with their polar diagrams directed radially outwards and overlapping. In one embodiment, the antennµ feed into a common load resistor through modulators each of which has a second input supplied from a phaseshifter energized from a common auxiliary oscillator, each second input being 45 degree phase displaced with respect to the adjacent inputs. The output from the common load is taken to a phase splitting device and next through two sampling devices, controlled from the auxiliary oscillator, to the mutually perpendicular deflection systems of a CRT display unit. The angular position of the display spot in the CRT screen is a function of the bearing of the received signal. The radial distance of the spot from the screen centre is a function of the signal field strength. In a second embodiment, both the frequency of the received signal as well as the target direction are displayed. In this case, the received signals at the load resistor control the sampling devices and the quadrature CRT deflecting voltages are of constant amplitude and are supplied by the auxiliary oscillator. When the output of the latter is amplitude modulated in accordance with the incident signal frequency, the distance of the display spot from the CRT centre is a measure of this modulation frequency.

Title: Blind riveting apparatus
IPC: B21J15/34
Filed: 1971-05-28
Abstract: 1397543 Blind rivetting AVDEL Ltd 26 May 1972 [28 May 1971] 18176/71 Heading B3U Blind riveting apparatus comprises abutment means 18, 20, a mandrel 12, first and second holding means 26, 28 and 30, 36 for holding the mandrel, the first holding means being reciprocable in a direction lengthwise of the mandrel to hold and move the mandrel between a rearward position, Fig. 2, in which the mandrel is held by the second holding means 30, 36 and a forward position, Fig. 1, in which the mandrel is disengaged from the second holding means, and means 42 for advancing a rivet forwardly along the mandrel from a position which is forwardly of the second holding means and which is rearwardly of the mandrel when the mandrel is in the forward position, wherein the first holding means and abutment means are operable to retract from the mandrel to allow a rivet to move forwardly along the mandrel. Actuation of the apparatus from the condition shown in Figs. 1 and 7, causes a ram 84 to move piston rod 90 and hence pulling jaws 26, 28 rearwardly, whilst the latter are gripping the mandrel until the mandrel head 16 has set the leading rivet 52 in a workpiece. During the setting of rivet 52 the rearward end of the mandrel passes through a fed river 54 and the rearwmost river 50 abuts a pivoted latch 44. When the mandrel reaches its rearmost position a ball 32 of detent 30 engages groove 36 in the mandrel and the jaws 26, 28, which are pivoted to the bifurcated end of the piston rod 90, begin to open, Fig. 2, due to the action of cam followers 140, 141, Fig. 7, on cams 144, 146. The rearward and opening movement of jaws 26, 28 continue, together with the simultaneous opening of jaws 38, 40, until the jaws 26, 28 reach their rearmost position. A stream of air is then delivered from jet 42 and drives the rivet 54 forwardly until it abuts the rearside of latch 44. The jaws 26, 28 now being to move forwardly and to close whilst the air stream is continued and, on reaching the head of the rivet 45, the jaws are closed sufficiently to move the rivet past the latch. At this stage a further rivet is fed to the jaws 38, 40 by a ram operated plunger. The jaws 26, 28 continue to move forwardly and eventually grip the mandrel. As the mandrel is moved forward the rivet 46 abuts and opens spring biased nose jaws 18, 20. The rivet 46 passes through the nose jaws, which close behind it, so that the apparatus is ready to commence a further cycle.
